BIOLOGICAL SPECIMEN STORAGE SYSTEM IN CRYOVIALS WITH INTEGRALLY ATTACHED SEGMENTS FOR THAWING.

摘要

The storage of biological specimens in liquid nitrogen is done in purpose-specific cryovials. These cryovials can be maintained indefinitely and with complete safety while submerged in liquid nitrogen. In the last few years, the storage of biological specimens in cryobags has become increasingly prevalent. The cryobags reduce the need for high-cost specialized manual labor. The fragility of the cryobags during cryopreservation and thawing is a drawback in their use. An important advantage of cryobags over cryovials is the creation of segments, from the filling tube, which can be selectively retrieved and thawed separately from the original cryobag. The invention described herein combines the advantages of storage within cryovials and cryobags, by the existence of integrally attached segments for thawing. The cryovials are connected with each other and bear integrally attached segments which can be easily cut off without having to remove the main body of the cryovial from the liquid nitrogen.
